The transmission number is transmitted to the first computing device.

BACKGROUND

The present invention relates generally to the field of Bluetooth™ beacons, and more particularly to load balancing network requests from a beacon on a computing device.

In computing, a wireless personal area network (WPAN) is a low-powered personal area network carried over a short-distance wireless network. The WPAN range may vary from a few centimeters to a few meters. The WPAN may serve to interconnect any number of ordinary computing and communication devices that many people carry around with them or have located in their home, office, etc. The WPAN may use short-distance technology such as Bluetooth™.

SUMMARY OF THE INVENTION

Embodiments of the present invention include a method, computer program product, and system for the load balancing of transmissions from any number of computing devices found in a physical environment. In one embodiment, a set of rules for assigning a transmission number to one or more computing devices is received. An indication from a first computing device is received. The indication includes a request for a transmission number. The transmission number for the first computing device is determined using the set of rules and a transmission window. The transmission number is transmitted to the first computing device. An advantage of this method, computer program product, and system is that devices are given a transmission number based on a set of rules and the transmission window. Each transmission number does not become overloaded with too many devices compared to another transmission number. This allows the server device to not become overloaded receiving notifications because computing devices can only transmit notifications to the server device during the computing devices assigned transmission window.

In yet another aspect, a method, a computer program product, and system are provide that allow for determining whether to update the transmission number for the first device based on the set of rules. Responsive to determining to update the transmission number for the first device based on the set of rules, the transmission number is updated for the first computing device using the set of rules and the transmission window. The updated transmission number is transmitted to the first computing device. An advantage of this method, computer program product, and system is that, when a transmission number has too many or too few computing devices assigned to it based on the rules, which would cause one transmission number to become more overloaded than another, the transmission numbers can be updated and transmitted to the devices so that the server can most optimally handle the notifications being received from the computing devices.

An embodiment of data processing environment 100 includes server device 110, computing device 120, and Beacon(s) 130. In an embodiment, server device 110 and computing device 120 are interconnected over network 102. Network 102 can be, for example, a local area network (LAN), a telecommunications network, a wide area network (WAN) such as the Internet, or any combination of the three, and include wired, wireless, or fiber optic connections. In general, network 102 can be any combination of connections and protocols that will support communications between server device 110, computing device 120, and any other computer (not shown) connected to network 102, in accordance with embodiments of the present invention.

In an embodiment, computing device 120 and beacon(s) 130 are interconnected over network 104. Network 104 can be, for example, Bluetooth™, Bluetooth™ low energy, near field communication networks, etc., or any combination, and include forms of wireless communications. In general, network 104 can be any combination of connections and protocols that will support communications between computing device 120, beacon(s) 130, and any other computer (not shown) connected to network 104, in accordance with embodiments of the present invention.

In an embodiment, server device 110 may be a laptop, tablet, or netbook personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, camera, video camera, video device or any programmable electronic device capable of communicating with any computing device within data processing environment 100. In certain embodiments, server device 110 collectively represents a computer system utilizing clustered computers and components (e.g., database server computers, application server computers, etc.) that act as a single pool of seamless resources when accessed by elements of data processing environment 100, such as in a cloud computing environment. In general, server device 110 is representative of any electronic device or combination of electronic devices capable of executing computer readable program instructions. In an embodiment, server device 110 may include components as depicted and described in detail with respect to FIG. 4, in accordance with embodiments of the present invention.

In an embodiment, server device 110 includes load balance program 112 and information repository 114. In an embodiment, load balance program 112 is a program, application, or subprogram of a larger program for the load balancing of transmissions from any number of computing device 120 found in a physical environment. In an embodiment, a physical environment is any physical area (e.g., a home, a condo, a store, an office, etc.) In an alternative embodiment, load balance program 112 may be located on any other device accessible by server device 110 via network 102. In an embodiment, information repository 114 may include load balance information used by load balance program 112 to determine the transmission number for computing device 120. In an embodiment, the load balance information includes, but is not limited to, rules for assigning a transmission number to computing device 120 based on the type of computing device, rules for assigning a transmission number to computing device 120 based on the location of the computing device 120, rules for the initial determining of a transmission number for computing device 120 or rules for reassigning an updated transmission number for computing device 120 based on the utilization of each transmission number, based on the historical length of stay of a device in the physical environment, etc. In an alternative embodiment, information repository 114 may be located on any other device accessible by server device 110 via network 102.

In an embodiment, load balance program 112 may determine a transmission number for a computing device and transmit the determined transmission number to the computing device. In an embodiment, load balance program 112 may receive rules for determining a transmission for a computing device. In an embodiment, load balance program 112 may receive an indication from a computing device requesting a transmission number. In an embodiment, load balance program 112 may determine a transmission number for a computing device using the received rules. In an embodiment, load balance program 112 may transmit the determined transmission number to the computing device. In an embodiment, load balance program 112 may receive an update the transmission number for a computing device based on changes to the physical environment. In an embodiment, load balance program 112 may transmit the updated transmission number to the computing device.

In an embodiment, load balance program 112 may include a user interface that allows a user to interact with load balance program 112. A user interface (not shown) is a program that provides an interface between a user and load balance program 112. A user interface refers to the information (such as graphic, text, and sound) a program presents to a user and the control sequences the user employs to control the program. There are many types of user interfaces. In one embodiment, the user interface can be a graphical user interface (GUI). A GUI is a type of user interface that allows users to interact with electronic devices, such as a keyboard and mouse, through graphical icons and visual indicators, such as secondary notations, as opposed to text-based interfaces, typed command labels, or text navigation. In computers, GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces, which required commands to be typed on the keyboard.

In an embodiment, server device 110 includes information repository 114. In an embodiment, information repository 114 may be managed by load balance program 112. In an alternative embodiment, information repository 114 may be managed by the operating system of server device 110, alone, or together with, load balance program 112. In an embodiment, information repository 114 may include, but is not limited to, rules for assigning a transmission number to computing device 120 based on the type of computing device, rules for assigning a transmission number to computing device 120 based on the location of the computing device 120, rules for assigning a transmission number to a computing device 120 based on a profile of the user of the computing device, rules for assigning a transmission number to a computing device 120 based on the predicted number of beacon(s) 130 the computing device 120 is going to interact with, rules for the initial determining of a transmission number for computing device 120 or reassigning a new transmission number for computing device 120 based on the utilization of each transmission number, etc. In an embodiment, information repository 114 may include information about the transmission window and transmission number. In an embodiment, the transmission window is the total amount of time that transmissions may be sent. For example, the transmission may be 10 seconds. In other words, all devices transmitting notifications to the server device 110 will do so at some time during the transmission window (i.e. 10 seconds). In an embodiment, the transmission number is a number assigned to a specific computing device indicating when that computing device can transmit notifications to the server device. Continuing the previous example, the transmission number may be one second in length and therefore, with a transmission window of 10 seconds there are 10 transmission numbers (i.e. second number one, second number two, etc.) In an embodiment, the transmission number can indicate the start of the transmission. Continuing the previous example, a computing device 120 with transmission number of the first second may transmit notifications to the server device 110 from the beginning of the first second until the end of the first second (i.e. 1.0 to 1.99). In an alternative embodiment, the transmission number can indicate the middle of the transmission. In an alternative example, a computing device 120 with transmission number of the first second may transmit notification to server device 110 a half second before the first second and a half second after the first second (i.e. 0.5 to 1.5). In an embodiment, a computing device 120 starts the transmission of the notifications to server device 110 within the transmission number associated.

Information repository 114 may be implemented using any volatile or non-volatile storage media for storing information, as known in the art. For example, information repository 114 may be implemented with a tape library, optical library, one or more independent hard disk drives, multiple hard disk drives in a redundant array of independent disks (RAID), solid-state drives (SSD), or random-access memory (RAM). Similarly, information repository 114 may be implemented with any suitable storage architecture known in the art, such as a relational database, an object-oriented database, or one or more tables.

In an embodiment, computing device 120 may be a laptop, tablet, or netbook personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, camera, video camera, video device or any programmable electronic device capable of communicating with any computing device within data processing environment 100. In general, computing device 120 is representative of any electronic device or combination of electronic devices capable of executing computer readable program instructions. In an embodiment, computing device 120 may include components as depicted and described in detail with respect to FIG. 4, in accordance with embodiments of the present invention. In an embodiment, there may be any number of computing device 120 in data processing environment 100. In an embodiment, computing device 120 may be a smart watch or wearable device. In an example, computing device 120 may be a smart watch of a person as they move throughout a baseball stadium. In another example, computing device 120 may be a mobile device of a customer as the customer moves throughout a retail store.

In an embodiment, computing device 120 includes beacon program 122 and information repository 124. In an embodiment, beacon program 122 is a program, application, or subprogram of a larger program for transmitting notifications based on a transmission number. In an alternative embodiment, beacon program 122 may be located on any other device accessible by computing device 120 via network 102. In an embodiment, information repository 124 may include a transmission number used by beacon program 122 to determine when to transmit notifications received by computing device 120. In an embodiment, the transmission number may be any value that represents a time in a transmission window. For example, the transmission number may be a digit, a time stamp, etc. In an alternative embodiment, information repository 114 may be located on any other device accessible by computing device 120 via network 102.

In an embodiment, beacon program 122 may receive a transmission number for computing device 120 and transmit notifications received by the computing device based on the received transmission number. In an embodiment, beacon program 122 may request a transmission number from load balance program 112. In an embodiment, beacon program 122 may receive a transmission number. In an embodiment, beacon program 122 may receive a notification from beacon(s) 130. In an embodiment, beacon program 122 may determine whether to transmit received notifications based on the transmission number received previously. In an embodiment, beacon program 122 adds the notification to a batch of non-sent notifications if the notification is not transmitted based on the transmission number. In an embodiment, beacon program 122 may transmit all received notifications in the non-sent batch of notifications if beacon program 122 determines to transmit based on the transmission number.

In an embodiment, beacon program 122 may include a user interface that allows a user to interact with beacon program 122. A user interface (not shown) is a program that provides an interface between a user and beacon program 122. A user interface refers to the information (such as graphic, text, and sound) a program presents to a user and the control sequences the user employs to control the program. There are many types of user interfaces. In one embodiment, the user interface can be a graphical user interface (GUI). A GUI is a type of user interface that allows users to interact with electronic devices, such as a keyboard and mouse, through graphical icons and visual indicators, such as secondary notations, as opposed to text-based interfaces, typed command labels, or text navigation. In computers, GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces, which required commands to be typed on the keyboard.

In an embodiment, computing device 120 includes information repository 124. In an embodiment, information repository 124 may be managed by beacon program 122. In an alternative embodiment, information repository 124 may be managed by the operating system of computing device 120, alone, or together with, beacon program 122. In an embodiment, information repository 114 may include, but is not limited to, the transmission number assigned to computing device 120, information about the computing device 120 such as identification information associated with the computing device (i.e., an email address, a phone number, etc.).

Information repository 124 may be implemented using any volatile or non-volatile storage media for storing information, as known in the art. For example, information repository 124 may be implemented with a tape library, optical library, one or more independent hard disk drives, multiple hard disk drives in a redundant array of independent disks (RAID), solid-state drives (SSD), or random-access memory (RAM). Similarly, information repository 124 may be implemented with any suitable storage architecture known in the art, such as a relational database, an object-oriented database, or one or more tables.

In an embodiment, beacon(s) 130 may be one or more device(s) that allows for wireless communication with another computing device. In an embodiment, beacon(s) 130 may be any networking device that forwards data packets to computing devices. In an embodiment, signal device(s) may be any networking device that is part of a wireless personal area network. In certain embodiments, beacon(s) 130 may be a device capable of Bluetooth™ communication that allows computing devices to connect. In certain embodiment, beacon(s) 130 may be include the ability for radio-frequency identification (RFID). In an embodiment, signal device(s) may be a combination of any of the above-referenced technology (e.g., two Wi-Fi devices and a Bluetooth™ device, a Wi-Fi device and two Bluetooth™ devices, etc.) or any other technology known in the art.

FIG. 2 is a flowchart of workflow 200 depicting operational steps for the load balancing of transmissions from any number of computing device found in a physical environment, in accordance with an embodiment of the present invention. In one embodiment, the steps of the workflow are performed by load balance program 112. In an alternative embodiment, steps of the workflow can be performed by any other program while working with load balance program 112. In an embodiment, workflow 200 can be invoked upon a computing device 120 attempting to transmit a notification to server device 110. In an alternative embodiment, workflow 200 can be invoked upon changes to the physical environment or rules that require a change to the transmission number assigned to a computing device 120.

Load balance program 112 receives rules (step 205). In other words, load balance program 112 rules for determining a transmission number to assign to any computing device that may be found in the physical environment. In an embodiment, the rules may include, but is not limited to, rules for assigning a transmission number to computing device 120 based on the location of the computing device 120, rules for the initial determining of a transmission number for computing device 120 or rules for reassigning a new transmission number for computing device 120 based on the utilization of each transmission number, etc. In an embodiment, the rules may include information about the total length of a transmission window (i.e., 10 milliseconds, 10 thousand milliseconds, 10 seconds, a timeout length of devices, etc.) In an embodiment, the transmission window is the entire window of time that all devices can transmit notifications, however, each device has assigned transmission numbers so each device can only transmit notifications during that transmission number. In an embodiment, transmission numbers are a segment or chunk of the transmission window (i.e. 1 millisecond of the 1000 milliseconds, 1 second of the 10 seconds, 10% of the timeout length of devices, etc.) In an embodiment, load balance program 112 may receive the rules from a user via the GUI discussed previously. In an alternative embodiment, load balance program 112 may retrieve the rules from information repository 114.

In a first example, the physical area may be a baseball park. Continuing with the first example, the transmission window at the baseball park is 10 seconds, the rules for initially assigning the transmission number to a device are that each transmission number (i.e. second number one, second number two, second number three, etc.) should cover 10% of the devices in the physical area, and the rules about reassigning a transmission number is if any transmission number receives covers less than 7% of the devices or more than 13% of the devices in the physical area then the transmission number will be reassigned/updated. In a second example, the physical area may be grocery store. Continuing with the second example, the transmission window at the grocery store is five thousand milliseconds. Here, the rules for initially assigning the transmission number is that the first device to request a transmission number receives the first thousand millisecond transmission number, the second device to request a transmission number receives the second thousand millisecond transmission number, the third device to request a transmission number receives the third thousand millisecond transmission number, the fourth device to request a transmission number receives the fourth thousand millisecond transmission number, and the fifth device to request a transmission number receives the fifth thousand millisecond transmission number. Further, the rules for reassigning the transmission numbers is that all transmission numbers need to have an equal number of devices assigned to the transmission number and if a device leaves so that a transmission number has less devices then another transmission number then a device will be reassigned a transmission number. In the second example, a device can be assigned more than one transmission number so that each transmission number has an equal number of devices assigned to it as compared to other transmission numbers.

Load balance program 112 receives an indication (step 210). In other words, load balance program 112 receives an indication from computing device 120 via network 102. In an embodiment, the indication may be a request for a new transmission number. In an alternative embodiment, the indication may be a request for an updated transmission number. In an embodiment, the indication may be a request for information from server device 110 related to one or more beacon(s) 130 that computing device 120 is within range and load balance program 112 now needs to assign a transmission number to computing device 120. In yet another embodiment, the indication may be that computing device 120 may have entered a physical area covered by server device 110 and therefore computing device 120 will need a transmission number. In the first example, discussed previously, a baseball fan enters the baseball stadium and as he is passing a hot dog vender, a beacon located on the hot dog cart of the hot dog vender sends an indication to the mobile device of the baseball fan. Here, the mobile device of the baseball fan sends the indication to a server device that manages all indications for the baseball stadium and the mobile device requests a transmission number for the mobile device. In the second example, discussed previously, a shopper enters the grocery store and as the shopper passes the threshold of the door of the grocery store, a location system indicates to the mobile device of the shopper that the shopper has entered the grocery store and therefore the mobile device sends an indication to the server device that manages all indications for the shopping center and the mobile device requests a transmission number for the mobile device.

Load balance program 112 determines a transmission number (step 215). In other words, load balance program 112 determines a transmission number for computing device 120 that requested the new transmission number in the previous step based on the rules received previously. In an embodiment, load balance program 112 may determine a single transmission number for computing device 120. In an alternative embodiment, load balance program 112 may determine multiple transmission number for computing device 120. In an embodiment, load balance program 112 may randomly assign a transmission number for computing device 120. Continuing the first example, discussed previously, load balance program 112 determines the transmission number for the mobile device of the baseball fan. Here, load balance program 112 accesses information repository 114 to determine the current transmission number allocation to other computing devices within the baseball park. Load balance program 112 determines the current allocation of transmission numbers is transmission number first second (9%), transmission number second second (11%), and transmission numbers third second through tenth second (10%). Therefore, load balance program 112 determines the transmission number for the mobile device of the fan should be transmission number first second because that is the transmission number with the lowest percentage allotment of devices. Continuing with the second example, discussed previously, load balance program 112 determines the transmission number for the mobile device of the shopper. Here, load balance program 112 accesses information repository 114 to determine the current transmission number allocation to other computing devices within the grocery story. Load balance program 112 determines that no other computing devices have entered the grocery story because the grocery store just opened. Therefore, load balance program 112 determines the transmission number for the mobile device of the shopper should be the first available transmission number, the first thousand millisecond transmission number.

Load balance program 112 transmits the transmission number (step 220). In other words, load balance program 112 transmits the transmission number determined previously to computing device computing device 120. In an embodiment, load balance program 112 transmits the transmission number via network 102. In an embodiment, load balance program 112 stores the transmission number assigned to computing device 120 in information repository 114. Continuing the first example, load balance program 112 transmits the determined transmission number first second to the mobile device of the fan. Continuing the second example, load balance program 112 transmits the determined first thousand millisecond transmission number to the mobile device of the shopper.

Load balance program 112 determines whether to update the transmission number (decision block 225). In other words, load balance program 112 determines whether there have been in any changes to the physical area covered by server device 110. In an embodiment, changes to the physical area may include, but are not limited to, the following: changes to the number of devices assigned to each transmission number, changes to the percentage of allocation of devices on each transmission number, changes to size of the physical area covered by server device 110, changes to performance of server device 110, changes to the location of the computing device 120 within the physical area, based on the historical length of stay of a device in the physical environment, based on the historical usage/performance information for server device 110 in the physical area, etc. If load balance program 112 determines there are changes to the physical area covered by server device 110, load balance program determines an updated transmission number and processing proceeds to step 230. If load balance program 112 determines there are not enough or no changes to the physical area covered by server device 110 so that load balance program does not need to determine an updated transmission number, then processing ends. Continuing with the first example, due to computing devices leaving the physical area, load balance program 112 determines that the current allocation of transmission numbers is transmission number first second (14%), transmission number second second (6%), and transmission numbers third second through tenth second (10%). Because, based on the rules discussed previously, no transmission number should have more than 13% of the allocation of computing devices, load balance program 112 determines that some computing devices with the transmission number first second should be updated to transmission numbers with the transmission number second second. Therefore, load balance program 112 updates the transmission number for mobile device of the baseball fan should be the transmission number second second and load balance program updates information repository 114 accordingly. Continuing with the second example, there have been no changes to the current allocation of transmission numbers for the grocery store and therefore load balance program 112 determines that the transmission numbers should not be updated and no changes are made to information repository 114.

Load balance program 112 transmits the updated transmission number (step 230). In other words, load balance program 112 transmits the updated transmission number determined previously to computing device computing device 120. In an embodiment, load balance program 112 transmits the updated transmission number via network 102. In an embodiment, load balance program 112 stores the updated transmission number assigned to computing device 120 in information repository 114.

FIG. 3 is a flowchart of workflow 300 depicting operational steps for transmitting notifications based on a transmission number. In one embodiment, the steps of the workflow are performed by beacon program 122. In an alternative embodiment, steps of the workflow can be performed by any other program while working with beacon program 122. In an embodiment, a user, via a user interface discussed previously, can invoke workflow 300 upon a user wanting to transmit a received notification on computing device 120 from beacon(s) 130 to server device 110. In an alternative embodiment, workflow 300 can be invoked upon computing device 120 entering a physical area covered by server device 110. In yet another embodiment, workflow 300 can be invoked upon computing device 120 receiving a notification from beacon(s) 130.

Beacon program 122 requests a transmission number (step 305). In other words, beacon program 122 requests a transmission number for computing device 120 from load balance program 112 on server device 110 via network 102. In an embodiment, beacon program 122 may request a transmission number from load balance program 112 upon computing device 120 receiving an indication from one or more beacon(s) 130. In an alternative embodiment, beacon program may request a transmission number from load balance program 112 upon computing device 120 entering a physical area that is covered by server device 110 and another computing device (not shown, such as a global positioning system or Wi-Fi triangulation location system) indicating to load balance program 112 that computing device is in a physical area covered by server device 110. In yet another embodiment, beacon program 122 may request an updated transmission number after a period of time of using a previously received transmission number (i.e. an expiration of an already received transmission number). In the first example, discussed previously, a baseball fan enters the baseball stadium and as he is passing a hot dog vender, a beacon located on the hot dog cart of the hot dog vender sends an indication to the mobile device of the baseball fan. Here, the mobile device of the baseball fan sends the indication to a server device that manages all indications for the baseball stadium and the mobile device requests a transmission number for the mobile device. In the second example, discussed previously, a shopper enters the grocery store and as the shopper passes the threshold of the door, a location system indicates to the mobile device of the shopper that the shopper has entered the grocery store and therefore mobile device requests a transmission number for the mobile device.

Beacon program 122 receives a transmission number (step 310). In other words, beacon program 122 receives a transmission number from server device 110 and load balance program 112. In an embodiment, beacon program 122 stores the received transmission number in information repository 124. Continuing the first example, beacon program 122 receives determined transmission number first second to the mobile device of the fan and stores the determined transmission number on the mobile device of the fan. Continuing the second example, beacon program 122 receives the determined first thousand millisecond transmission number to the mobile device of the shopper and stores the determined transmission number on the mobile device.

Beacon program 122 receives a notification (step 315). In other words, beacon program 122 receives a notification from at least one of the beacon(s) 130 via network 104. In an embodiment, the notification may be in the form of a universally unique identifier (UUID). A UUID is an identifier standard used in software construction that may be a 128-bit value and the meaning of each bit is defined by any of several variants. In an embodiment, the notification may include a major number, a minor number, and a TX power level in 2's compliment, as known in the art. In an embodiment, the notification may include any number of hex data. In an embodiment, the notification may be in any form that identifies, to beacon program 122, the beacon(s) 130 that are transmitting the notification that beacon program 122 receives. In the first example, discussed previously, a baseball fan enters the baseball stadium and as he is passing a hot dog vender, a beacon located on the hot dog cart of the hot dog vender sends an indication to the mobile device of the baseball fan. In the second example, discussed previously, a shopper enters the grocery store and as the shopper enters aisle three, a beacon located in aisle three sends an indication to the mobile device of the shopper.

Beacon program 122 determines whether to transmit (decision block 320). In other words, beacon program 122 determines whether to transmit all previously received notifications that have not been sent to server device 110 based on the transmission number for computing device 120. In an embodiment, beacon program 122 determines if the current time span in the total transmission window is at the transmission number assigned to computing device 120. In other words, a total transmission window, as discussed previously, exists for the server device 110. Beacon program 122 determines whether the current time in the total transmission window is at a transmission number was received previously and assigned to computing device 120. Beacon program 122 determines this by comparing the current timestamp at the time to transmit to the transmission window time. The transmission window time on computing device 120 is synched with the server device 110. In other words, the server device 110 has a clock that indicates the time window and when this time window starts and computing device 120 has a clock that synchs with the clock of the server device 110 so that the time window on the computing device matches the server device. Computing device 120 can then use the synched time window to determine whether the timestamp at the time to transmit is within the transmission number assigned to computing device 120. In an alternative embodiment, clocks can be synched between server device 110 and computing device 120 using a “seed” time or an “offset”. The “seed” time or “offset” is a period of time that is added or removed from the internal clock of the computing device 120 to make the internal clock plus or minus the “seed” time or “offset” equal to the internal clock of the server device.

In the first example, discussed previously, server device covering the baseball stadium has a transmission window of 10 seconds. Here, the baseball fan receives the indication on his mobile device from the beacon located on the hot dog cart at the fourth second of ten second window. Beacon program 122 determines not to transmit the notification to the server device because the transmission number of the mobile device of the baseball fan is the first second and currently, beacon program 122 is at the fourth second of the ten second window. In the second example, discussed previously, server device covering the shopping center has a transmission window of five thousand milliseconds. Here, the shopper receives the indication on their mobile device from the beacon located in aisle three at the first thousand millisecond of the five thousand millisecond window. Beacon program 122 determines to transmit the notification to the server device the transmission number of the mobile device of the shopper is the first thousand millisecond and the currently, beacon program 122 is at the first thousand millisecond of the five thousand millisecond window.

If it is determined that it is not time to transmit (decision block 320, no branch), beacon program 122 adds the notification to a batch of notifications (step 325). In other words, beacon program 122 adds the received notification to a batch of notifications. In an embodiment, the received notification may be the first notification that is waiting to be sent when the transmission number for computing device 120 occurs. In an alternative embodiment, the received notification may be added to a batch of already received notifications that have not been sent yet and are waiting to be sent when the transmission number for computing device 120 occurs. In an embodiment, the notifications are stored in information repository 124. In an embodiment, the batch of received notifications that have not been sent yet are stored in information repository 124. In the first example, discussed previously, beacon program 122 determines that it is not time to transmit the notification received by the mobile device of the baseball fan, therefore, beacon program 122 adds the notification to information repository 124 found on the mobile device of the baseball fan. Here, the notification is added to a batch of notifications previously received and not previously sent to server device 110.

Beacon program 122 determines whether there is a new notification (decision block 330). In other words, beacon program 122 determines whether computing device 120 receives a notification from at least one of the beacon(s) 130 via network 104. If beacon program 122 determines that computing device 120 receives a notification from at least one of the beacon(s) 130 via network 104 (decision block 330, yes branch), beacon program 122 receives a notification (step 315).

If beacon program 122 determines that computing device 120 does not receive a notification from at least one of the beacon(s) 130 via network 104 (decision block 330, no branch), beacon program 122 determines whether the time is at the transmission number (decision block 335). In other words, beacon program 122 determines whether to transmit all previously received notifications that have not been sent to server device 110 based on the transmission number for computing device 120. Similar to decision block 320, beacon program 122 determines if the current time span in the total transmission window is at the transmission number assigned to computing device 120. If beacon program 122 determines that it is time to transmit based on the time being at the transmission window (decision block 335, yes branch), beacon program 122 transmits the batch of received notifications that have not been transmitted yet (step 340), as discussed below.

If it is determined that it is time to transmit (decision block 320, yes branch), beacon program 122 transmits the batch of received notifications that have not been transmitted yet (step 340). In other words, beacon program 122 transmits all received notifications, at the time of beginning of the transmission, that have not been previously sent to server device 110 via network 102. Server device 110 includes a program (not shown) to handle received notifications and handle them accordingly, as known in the art. In the second example, discussed previously, beacon program 122 determines that is it time to transmit the notification received by the mobile device of the shopper, therefore, beacon program 122 transmits the notification to the server device that covers the physical area of the grocery store. In an embodiment, if a transmission fails, beacon program 122 will attempt to transmit all received notifications in the batch when the transmission number next occurs.
